It has been a while since we acquainted you with Reactive Grip, a motion controller with tactile feedback for playing RPG games with swords or knifes. Since then a lot of improvements have been made to the Reactive Grip since it was first revealed at Game Developer Conference (GDC) 2013 and now it is all set to hit Kickstarter soon (by the end of October). It is lighter and slimmer with the addition of ergonomically integrated trigger, thumbstick and buttons. The feedback of this motion controller has got even better and it is compatible with Sixense STEM tracking system with mounting options for trackers such as Razer Hydra. The controller is 7.25 inches (19 cm) as compared to the 11 inch (28 cm) height of the previous Reactive Grip. So, it was high time we got a personal one-on-one view of what William Provancher has to say about this cool technology and the subsequent product created using it. We got the chance to get an exclusive interview with William Provancher, Associate Professor at University of Utah and the creator of Reactive Grip from Tactical Haptics, and here is how it went.
